--- Comment #9 from Travis James <Tjames6858 at gmail.com> ---
I'll update this bugzilla thread since it seems to be the most recently
updated. I went ahead and recompiled the v3.17.2 kernel with acpi debugging
messages and set the following values for acpi.debug_layer and
acpi.debug_level:
acpi.debug_layer: 0x10 (ACPI_NAMESPACE)
acpi.debug_level: 0x200 (ACPI_LV_EXEC)
and the values I got out of doing that when first holding down the Fn key, and
then pressing Fn+F5 4 times and then Fn+F6 4 times, and then releasing the Fn
key are:

By contrast, here is what it looks like when I press down the Fn key for a
short period of time, then press F3 (to do Fn+F3, or "decrease keyboard
brightness) 4 times and then do Fn+F4 ("increase keyboard brightness") and then
release the Fn key:

I still have no great understanding about how the AML system works, but at
least Ive got ACPI namespace paths out of it. looks like I'm getting namespace
paths and everything out of the embedded controller.
